Procedure: Take one of the coils and connect it to the
galvanometer. Use the cylindrical magnet to generate a changing
magnetic field around the coil and note the reading of the
galvanometer as the field changes. Thrust the N pole of the magnet
into the coil and note the effect on the galvanometer. When the
needle has come to rest, withdraw the magnet as quickly as
possible. Note the effect on the direction of current flow. Reverse
the magnet and...
